Russian opera star Dmitry Hvorostovsky has died of brain cancer at age 55, his family says.
The Siberian-born baritone died "peacefully" and surrounded by relatives at a hospice near his home in London, a statement on his Facebook page said.
"May the warmth of his voice and his spirit always be with us," it said.
Hvorostovsky was diagnosed with a brain tumor in 2015 and had all but given up live performances by the end of 2016.
He made his final public appearance at a concert called Dmitri And Friends at Austria's Grafenegg Festival in June.
The Vienna State Opera announced that month that that he had canceled all upcoming performances.
Hvorostovsky, who was born in Krasnoyarsk in October 1962, has recorded more than 40 albums.
Russian President Vladimir Putin expressed condolences to Hvorostovsky's family, friends, and fans, saying that his work was an achievement belonging "not just to [Russian] but to world culture," according to a Kremlin statement.
It said he had been honored as a People's Artist of Russia.
Hvorostovsky is survived by his wife, Florence Hvorostovsky, and their two children, as well as his twin children from a previous marriage, and his parents.
